Why earthing is importantThe installation and maintenance of an effective low resistance earthing system is essential for any modern facility for three key reasons:

• Protectionofpersonnelwhoworkwithinthefacility

• Protectionofequipmentsoastominimizedowntime,serviceinterruptionsandreplacementcosts

• Ensureselectricalnoisereductionwhichminimizesvoltagepotentialsbetweeninterconnectedequipment

The requirement for effective earthing is critical when considering the following applications:

• Lightning Protection

• Power generation, distribution and transmission

• Telecommunications

• Reduction of static electricity

Earthing Principles


The Importance of Low Soil Resistivity

While many factors influence the effectiveness of an earthing system, it is the resistance of the earth itself (earth / soil resistance) which has the greatest influence on the overall impedance of an earthing system. Several factors such as soil composition, moisture content, seasonal weather, mineral content and possible contaminants determine the resistivity of the soil.

Soil types and composition vary greatly from one site to the next.

• Rich dark soils high in organic content are typically good conductors due to the retention of moisture which aids in the dissipation of electric currents.

• Sandy soils are ineffective in retaining moisture content due to the high drainage effect of sand and typically have a higher impedance.

• Rocky ground retains virtually no moisture content and as a result is very high in resistance.

The Key Parameters of an Efficent Earthing System

• Excellent electrical conductivity

• Low Earth Resistance and Impedance

In order to achieve a low resistance and impedance earth, all connections should be as short and direct as possible. Maximising the surface contact between the soil and all electrodes and conductors is essential for efficient performance.

• Conductors capable of withstanding high fault currents

• Robust Mechanical Connections

All connections should be robust to facilitate a long working life.

• High Corrosion resistance

Materials chosen for earthing systems should offer an acceptable compromise between cost and longevity. It is essential that compatible metals are used in the installation of an earthing system to minimize corrosion. See our detailed section on corrosion on page 8

• Equipotential Bonding

The elimination of dangerous step and touch potentials is achieved

Earthing Principles

through equipotential bonding of all earths.


Typical Resistivity Readings for Varying Soil Types

SoilType TypicalResistivity Range–ohm-m

Wet lands 2 – 2.5

Rich Organic Soil (Loam & Clay) 4 – 150

Sand 90 – 8500

Sandy Gravel 300 - 500

Rocky Ground 1000+

Moisture content is the single largest influence on soil resistivity and in most cases the higher the moisture level of the soil the lower the soil resistivity. The installation of a deep driven earthing electrode which reaches the water table beneath the surface represents an ideal earthing system.

Seasonal weather conditions play a significant role in influencing soil resistivity levels over an extended period of time.

Areas which are subjected to high annual rainfall will typically have lower soil resistivity levels in comparison to areas which are prone to sustained hot temperatures and drought like conditions, which will result in increased soil resistivity levels. Regions where temperatures fall below freezing will see sharp increases in soil resistivity as the moisture content within the soil freezes.

Earthing Principles


earth bars and Transient Earth Clamps combine to create a safe equipotential earth plane which serves to protect personnel and equipment. See pages 32-35, 44-47.

Earth Pits

LPI offers a selection of light weight and heavy duty earth pits which are suitable for most types of earthing and lightning protection installations. See pages 42-43.

Earth Enhancing Compounds

Earth enhancing compounds are applied in and around conductors in an earthing system to reduce soil resistivity and lower earth impedance. See pages 36-39.

Chemical Earth Rods

The installation of a Chemical Earth Rod provides for a low impedance earth in locations of high soil resistivity. Ideal for installation in locations where space constraints make it difficult to install extensive earthing systems. See pags 40-41.

The Components Required to Achievean Efficent Earthing System

LPI offers a wide selection of earthing products which are used in the installation of low resistance earthing systems.

Earth Rods, Tapes and Clamps

LPI copperbonded, solid copper and stainless steel earth rods in combination with copper tapes and connecting clamps form the key components of an earthing system, which provides for the safe and efficient transfer of fault currents and lightning energy into the earth mass. See pages 9-27, 52-55.

Exothermic Welding Permanent Connections

The use of exothermic welding is a safe and efficient way of providing a permanent connection between conductors. See pages 28-31.

Earthing Principles

Designing for an Earthing System

There are several key factors to consider when planning the design of an earthing system.

• Applicable standards and codes to be followed:

For power system earthing IEEE 80 or other international derivates of this are widely used. These standards are usually mandatory and some level of expertise is needed to undertake designs to these standards.

For lightning protection / static earths commonly used standards are IEC62305, AS1768, NFPA 780 These standards are often not mandatory, but provide recommendations.

• Type of facility and the layout of the site with particular consideration given to the available space

• Level of soil resistivity at site

• Influence of seasonal weather conditions on soil resistivity

• Corrosive nature of soil and consequently materials chosen for use

• Expected life of the facility, once again affecting material choices

• Future extensions

• If applicable the status of any existing earthing system

• Step and Touch potentials

• Volume of pedestrian traffic

• Finally but most importantly, the quality and compliance of hardware used in the earthing system installation is a major determinant of the reliability of the earthing system. This is why some standards for design also have requirements associated with testing and certification of components. Some applicable testing standards include IEEE 837, and EN 50164

The consequences of a badly designed and installed earthing system not only pose dangers to the safety of site personnel and equipment, but usually presents an expensive and difficult task to remedy after the construction phase has been completed. Often remedial work is substantially more expensive than the initial material costs.

LPI can offer professional advice and / or complete earthing system design to relevant standards. See page 58 for more details.

For more basic earthing system designs, please see our online earthing calculator per details on page 56.


Earthing Principles

Choice of materials for rodsThe materials chosen for earth rods in particular have a great bearing on the service life of the installed earthing system. For this reason the following points need to be given serious consideration.

Mechanically clad rods are almost universally found to be inferior in service life compared to electroplated rods. This is true even in relatively benign earthing conditions. This is true for copper and stainless steel clad rods to much the same extent. Several independent studies around the world have concluded this.

For corrosive environments such as coastal conditions, reclaimed land, acid soils and the like, solid 316 stainless steel rods are recommended.

There are many variants of stainless steel rods in the market place, several key points need to be understood. Solid 304 stainless steel (sometimes known as 18/8) in a buried and corrosive environment will give a poor service life compared to 316 stainless steel. This is due to the differences in chemical composition and consequent grain structure of the steel. 316 stainless steel is used almost exclusively in marine industries for this reason, and is the recommended choice of material for earth rods in corrosive environments.

Beware that some earth rods are sold as stainless steel when in fact they are a thin stainless steel cladding on a steel earth rod which will provide negligible improvement to service life in corrosive earthing situations compared with a plain mild steel rod.

The next most cost effective option in corrosive soils is solid copper rods which will be more resistant to corrosion than an electroplated rod, and will handle heavier fault currents for the same diameter than stainless steel or electroplated rods.

Electroplated copper rods are the most cost effective choice for non corrosive benign soil conditions.


Earth RodsEarth rods are commonly utilized as the principle earth electrode in the design and installation of an earthing system.

LPI offers a selection of copperbonded steel, solid copper and stainless steel earth rods which are manufactured to meet International Standards such as UL 467.

The copperbonded steel cored rod is the most commonly used type of earth rod due to its overall combination of strength, corrosion resistance, low resistance path to earth and cost effectiveness. The LPI copperbonded rods are manufactured by bonding a copper layer to a steel core

Resistance decrease can be obtained by increase in each driving depth.

through an electrolytical process that ensures a perfect and even bonding between the steel and copper.

The rod finishing is free of imperfections or peeling. The copper layer, whose minimum thickness is 254 microns (10 mils) is individually and rigorously controlled by a modern set of electronic gauges.

Solid copper and stainless steel earth rods offer a high level of corrosion resistance suitable for installation in aggressive soil conditions.

Earth Rods


Copper Rods – A Question of QualityThe life expectancy and performance of an earthing

Cost Effective Earth RodsThere are many factors to consider when choosing the most cost effective earth rod for your application.

• Copperbonded earth rods typically have a life expectancy of + 30 years in benign (ie non corrosive) soil conditions. Substantially less life can be expected in corrosive or wet conditions.

• Stainless Steel and Pure copper earth rods are typically used in corrosive or continually wet applications.

• Increasing the diameter of the earth rod plays a minor role in lowering earth resistance. By doubling the diameter of the rod a 10% improvement in earth resistance is gained with a 350% increase in the cost of the rod.

• Where space constraints restrict the installation of an extensive earthing system, deep driven rods provide a cost effective solution in achieving a low resistance earth, but depending on the configuration may still provide a high impedance level.

system can be influenced by the type and quality of the copper earth rod that is installed. The following photo shows two copper earth rods which have both been subjected to the same pressure load test.

The lower rod in the photo below, is an LPI copperbonded rod which is free from cracking or tears to the outer sheath following the pressure test. The copperclad rod on top shows clear evidence of cracking and tearing to the outer sheath. The installation of earth rods involves driving the rod into the ground, it is this process where inferior quality copper rods are likely to be damaged resulting in cracks or tearing to the outer sheath which will significantly reduce its serviceable life and placing the integrity of the whole earthing system at risk.

Driving StudHigh tensile steel driving stud which can be used many times over and is

suitable for power hammering.

CouplingWhether connecting rod to rod or driving stud to rod the high strength copper alloy coupling is counter bored to protect the earth rod threads from damage and subsequent corrosion.

Earth RodCopperbonded earth rods are made from high tensile low carbon steel and each rod is manufactured by molecularly bonding 99.9% pure electrolytic copper to the low carbon steel core in accordance with national and international standards such as UL 467. Threads are rolled onto the rod ensuring an even copper covering which eliminates the risk of chipping whilst driving.

Exothermic Welding

Exothermic WeldingExothermic welding is a cost effective method of completing a high quality electrical connection. The process is simple to follow and through the use of a high temperature reaction a long lasting, quality electrical bond is created between conductors.

Advantages1. Does not deteriorate with age as the connections are

permanent.

2. Does not loosen as the Exothermic connections create a permanent molecular bond.

3. Excellent corrosion resistance.

4. Electrical characteristics are higher than typical mechanical connections.

5. Does not increase resistance above that of the conductor.

6. No external power or heat is required to make connections.

7. Quality can be assessed visually.

8. Easy and simple to install.

* Refer to LPI® Exothermic brochure for full details on the range of available Exothermic welding connections and products.


Exothermic Welding

Exothermic welding processThe exothermic welding process is a method of making electrical connections of copper to copper or copper to steel in which no outside source of heat or power is required.

In this process, granular metals (granular copper oxide and aluminium) are placed from a container into a graphite crucible and ignited.

The reduction of copper oxide by the aluminium (exothermic reaction) produces molten copper and aluminium oxide slag.

The slag floats to the surface and the disk melts, allowing molten copper to flow into the weld cavity and complete the weld. The weld is allowed to solidify.

The mold is removed and made ready for the next weld. The process takes seconds to complete.

An Exothermic connection is a perfect molecular bond which provides permanent conductivity over the whole section of the weld, due to molecular bonding between the metal surfaces.

The mold is removed and made ready for the next weld. The process takes seconds to complete.


Exothermic Welding

Making an LPI® Exothermic Connection1. Fit a handle clamp with a pre-

determined carbon mold as per your specification.

2. Remove all moisture from the mold through the use of a blow torch.

3. Fit a dry and clean conductor into the mold and close the handles to lock the carbon mold.

4. Drop the metal disk into the mold so as to hold the weld metal powder in place.

5. Place the weld metal into the mold.

6. Connect the universal igniter (one required per weld) to the ignition lead.

7. Position the end of the universal ignitor lead so that it sits in the weld metal powder.

8. Close the lid of the mold.

9. Press the ignition button on the remote ignition unit.

10. Open the mold after the metal solidifies, remove any slag from the mold.

11. Clean the mold for the next connection.

Insulated Joint Protector

LPI’s Insulated Joint Protector (IJP100) is designed for protection of insulated joints in oil or gas pipelines. With long lengths of insulated pipeline, induced voltages in the pipes caused by local lightning or power line fault activity can be in the order of tens of kilovolts. For protection against insulated joint break down, LPI developed the IJP100 which is connected directly across the insulated joint. In its inactive state the IJP presents an effective open circuit (1010 Ω) across the joint. Should the insulated joint voltage exceed the breakdown voltage of 350V, the IJP will immediately conduct to safely pass the surge current to ground and thus bypassing the insulated joint. After conducting, the IJP will automatically reset to its inactive state.

Transient Earth Clamp

LPI’s Transient Earth Clamp (TEC100) prevents earth potential differences by operating only under transient conditions to effectively clamp all connected earths together. Under normal conditions, the TEC100 presents an effective open circuit. Once the earth potential difference exceeds the breakdown voltage of the TEC100, conduction immediately occurs and the earth potentials are equalised. The TEC100 is a self-restoring device and has a life of over ten thousand operations.

Chemical Earth Rods

LPI’s Chemical Ground Rod provides a low impedance earth to effectively dissipate lightning and electrical fault currents. The Chemical ground rod is ideal in situations where space is restricted and normal lightning earths such as radial and grid type systems cannot be installed.

The LPI chemical ground rod is combined with LPI’s Reslo and mineral salts to provide a maintenance free earthing installation, which provides a low resistance earth. The Chemical ground rod provides extended reliable service due to its robust design, this includes a 63.5mm (Dia) copper tube, used in conjunction with mineral salts, LPI Exothermic welded connections and Reslo.

• 2m or 3m x 63.5mm Copper Tube • 70mm Cable (Pigtail) Exothermic welded connection or mechanical fixing• Mineral Salts• LPI® RESLO

Through the use of LPI’s Exothermic welding material a pigtail is pre-welded to the rod prior to supply, this allows for ease of bonding for the Chemical Ground rod and ensures a low impedance current path is maintained.

Earth Pits

Earth Bond Inspection PitLPI® Earth Bond Inspection Pit is a multi-purpose earth pit and bonding point which can be installed internally within a structure or externally to a structure. The earth bond inspection pit consists of a rectangular heavy duty earth pit and a six way earth bar mounted internally.

This product is ideally suited as a central bonding point for all earths at site or, alternatively, as a reference bonding point for selected earths. Initially designed for use in conjunction with a chemical ground rod at a roadside telecommunication base station site, this product provides the installer with a variety of options with respect to bonding and earthing applications.


Earth Bars

Earth Bars and Disconnect LinksCorrect Bonding is essential to create an equipotential earth plane between service earths and equipment under fault or transient conditions. The equipotential plane ensures that voltage differentials are not created between earths under fault conditions and ensures the safety of all personnel and equipment.

LPI offers a wide selection of earth bars and disconnect links which provide a single point earthing and bonding location. All earth bars and disconnect links are supplied with a plastic “non-corrosive” base suitable for exposed installation.
